[sdiy] Filter slopes

[Elain Klopke]

Hey all,

I was reading an article about the spectral content of various instruments
(woodwinds and strings) and while they didn't have any circuits, there were
some tables showing cutoff frequencies and high and low slopes. Several of
the pictures looked like bandpass filter responses with different slopes on
each side. How would I go about doing that? Is the slope determined by the
gain of the op amp in an active filter? If it's that easy, would it be a
highpass filter followed by a lowpass filter each with their own gain
settings?
